My invention relates to means whereby sliding windows may be made weather-proof and at the same time permitting the windows to be easily operated; and although I have illustrated the invention inconnection with a double type of car window, it will be understood that the invention is equally applicable to other types of windows.

For purposes of exemplification, the invention has been shown applied to a railroad passenger car window to which it is especially applicable and whereby certain parts at present involved in'passenger car windows are eliminated, while at the same time a better weather sealing or stripping of the usual double windows of a car is obtained.

a M invention also involves an improved win ow guide and window-locking and holding means for maintaining the window in locked or in the desired raised position, while at the same time providing easy mani ulation of the windows.

e ob'ects and advantages of m invention'will e readil compre ended fi'om the following detaile description of the accompanymg drawings wherein Figure l is an elevation of a car window as viewed from the car interior, with an intermediate portion broken away. Figure 2 is an enlarged cross-sectional view taken substantially on the line 2-2 of Figure 1. 7

Figure 3 is an enlarged vertical sectional view taken substantially on the line 3-.-3 of Fi ure 1', as viewed by the arrows.

igure 4 is an enlar ed perspective view of a portion of a side 0 the outside window.

Figure 5 is a rspectiveview of a portion of the win ow frame, weather strippinlg, outside window guide and locking rac My improved windowconstruction is especially intended for railroad passenger cars in connection with the double,'namely the inside and outsidewindows of a passenger car.

In Figure 1 a portion 015 the interior car wall an a window casing is shown; a porand in the specific embodiment it is shown closed position, see Fi tion of the window casing being more clearly shown at 10 in Figure 2, provided with a metallic finish panel 11 on the car interior; while the outer wall is provided with the sto rail or member 12.-

he window casing on the inner side is shown provided with a curtain slide rail 13. Slidably mounted intermediate of the stop rail 12 and the curtain slide 13 are. the outside window 14 and the inside window 15. 4 Secured to the opposite sides of the window casing .or opening and adjacent to thestop rail 12 is a vertically disposed slideformin channel member 16, referably made 0 metal, with the channel 0 f suflicient depth and width to receive the side sash members 17 of the outside window 14 and constitute a slidewa for the sash; the channel member 16 being suitably secured in lace as for exam le by the screws -18; it ingunderstood t at thechahnel members 16 extend throughout the height of the window. opening. p

The channel members 16 on each side of the window opening are identical, with the outer leg or sideof each channel member 16 of greater width and bent into the inwardly disposed groove forming portion 19. This groove forming portion is provided with a weather strip 20 of suitable 'eldable mate-- rial, such as rubber or felt, w ich'is clamped in lace'in the groove forming portion 19.

he channel member'16, at each side of the window opening at an intermediate point in the channel, is formed to provide a vertically extending rack forming rib 21 which is provided with vertically spaced apart shoulders 22, while the rib intermediate 'of the respective shoulders 22 is made to slope inwardly toward the next subjacent shoulder as at '23 in Figure 5. Adjacent to the lower, end, the rib 21 is provided with a notch or {slot 24, thus providing the two locking shoulders or stops 25, 26, adapted to reoeivethe end of the locking rod 27 therebetweenrwhen the window is in full re 1. The side sash mem rs 17 of the outer 4 window are shown provided with the sash protector 28, preferably of sheet metal and of channel formation to fit snugly about the sash sides as shown in Figure 2. The rotector 28 isvbent to provide a rib 29 w ich is embedded in the side sash member 17 and is adapted to receive the rack forming rib 21 of the slideway channel 16. The protector member 28 is securely fastened to the outer sash 14 in any suitable manner as by the screws 30. The side of the protector member 28, disposed toward the car exterior, is of greater width so as to extend slightly beyond the weather strip and the outer vertical edge of this side is preferably flanged outwardly as at 31 to lap the side of the weather strip 20 as shown in Figure 2; and the protector 28 is preferably made wider at the bottom to permit itto lap the bottom sash rail 32 and also be secured thereto as shown in Figure 4.

The bottom member 32 of the outer sash 14 is shown provided with finger grasping members 33, 33 which control the looking or latch rod 27 and retract the rod 27 from en gagement with the rack rib 21 when the members 33, 33 are pressed together.

The window sill, shown at 34, is provided with a shoulder at 35 disposed on. the innersuitable flexible material; the strip 36- being preferably of slightly greater width, than the thickness of the sash.

-The strip 36 is held in place by a suitable strip 37 ,preferably of metal, and the strip 37 held in place by screws 38 which extend through the weather strip 36 and into the bottom member 32 of the sash.

By dishin the sash as shown, the outer free longitu inal edge of the weather strip 36 is bent downwardly into snug relation with the window-sill 34; while the inner longitudinal edge of the weather strip 36 is in contact with the shoulder 35 of the window-sill, thus completely sealing the contact between the bottom of the outer sash 14 and the window-sill.

In order to provide an air-tight condition at the top of the outer sash, I provide the top rail or member 39 of the outer sash 14 with: a weather strip 40 extending longitudi nally of the sash preferably secured in place by an angle plate 41 which is secured to the window-sash by screws as at 42.

Secured vto the car wall within the sash receiving space above the window opening is a metal trough member 43 suitably secured .in place as forexample by screws as at 44-.

Inorder to properly position the lower trough portion and 'to position the lower longitudinal edge of the weather-strip 40 so it will enter or seat in the trough, I provide a wedge shape block 45 to the rear of trough member 43 held in (place on the car wall by the screws. 44; an also provide a wedge shape block 46, secured to the sash by the screws 42, rearward of the weather-strip. It is apparent that the lower free longitudinaledge of the trough will receive the lower rack forming rib and sash guide shown formed integral with the slideway forming channel member 51 which is suitably secured to opposite sides of the window casing and extending from top to bottom.

The rack'forming rib and sash guide 50 is similar in construction to the rib 21 de.-

scribedin connection with the outer sash and shown in Figure 5 and the lower rail of the inner sash is also shown provided with similar finger grasps and control members 33, see Figures 1 and 3, which control the laterally movable latch rods 27 and retract them from engagement with the stop shoulders of the rack.

It is apparent from the construction shown and described that comparatively-free 3 sliding sashes are provided by the metal to metal contacts .at the sides of the sash, while at the same time a comparatively simple weather sealing construction is provided, I

whereby an air-tight condition at the sides, top andbottom of the outer sash is obtained and an effective air sealing condition with the sides of the inner sash is also provided, while at the same time providing means which will permit the windows to be raised readily and will not be affected by moisture.

As my invention is especially applicable to railroad passenger car windows, it has i been so shown and described, but it is apparent that the invention is applicable to any sliding type of window.

I have shown what is believed to be a simple embodiment of the invention, which has been described in terms employed merely as terms of description and not as terms of.

limitation, as modifications may be made without, however, departing from the spirit of my invention.
